The very concept of "commissioning" an "AI artist" is as ridiculous as it is hilarious.
You see... when you "commission an artist" the first thing you have to do is sit down with them, and describe, in detail, what you want.
All an "AI artist" does is feed what you told them into a robot, get a bunch of low quality shitty facsimiles of art out the other end, then select the least bad one to sell you for money.
But... the effort and time it takes to describe your desired image to another person is just the same effort and time as describing your desired image to the robot. All the "artist" does here is slow down the process then charge you money.
